option 1 is correct.

logic gateis an elementary building block of a digitalcircuit. Mostlogic gateshave two inputs and one output. At any given moment, every terminal is in one of the two binary conditions low (0) or high (1), represented by different voltage levels.

NAND it is a combination of AND and NOT gate.

Nand is the universal logic gate

PV=nRTif n is doubled then pressure will be doubled

P is open key, X is Ammeter, Y is voltmeter, Z is resistance.

P is switchX is ammeter as it is applied in series with battery source.Y is voltmeter to know voltage across resitance wire.Z is variable rheostat.

Total resistance = 4*4/8+2= 4 ohm

now current= 4/4= v/R1 ampnow voltage across 2 ohm= 2*1= 2 volt

82=W*1000/0.3750.375*82=W*10000.375*82/1000=WW=30.75/1000W=0.03075

Total resistance= 6*6/12= 3 ohmPotential will be 6 volt only it will be same as it's a parallel connection

A=सदिश/सदिश का मापांकसदिश का मापांक=√503i+4j-5k/√50

It is a force exerted at a distance from an object’s axis of rotation.A torque applied to an object will cause it to rotate around a pivot point. The pivot point is known as the axis of rotation, and the perpendicular distance of the force from the axis of rotation is known as the moment arm. This is why torque is also referred to as a moment of force.Torque is a rotational force. Just as a linear force is a push or a pull, a torque can be thought of as a twist to an object.

14/5 and 6/5 is the answer to this question

In optics, the refractive index or index of refraction of a material is a dimensionless number that describes how fast light propagates through the material. It is defined as c/v where c is the speed of light in vacuum and v is the phase velocity of light in the medium.

whats the formula of range in this solution pls ???

(A+B)²=A²+B²+2ABcos(x)(A+B)²=A²+B²+2ABcos(x)

|A|=1,|B|=1,|A+B|=1|A|=1,|B|=1,|A+B|=1

=>1²=1²+1²+2(1)(1)cos(x)=>1²=1²+1²+2(1)(1)cos(x)

=>cos(x)=−(1/2)=>cos(x)=−(1/2)

=>x=120°=>x=120°

Angle between A and B = 120°

=> Angle between A and -B = 60°

(A−B)²=A²+B²+2ABcos(x)(A−B)²=A²+B²+2ABcos(x)

=>(A−B)²=1²+1²+2∗1∗1∗(1/2)=>(A−B)²=1²+1²+2∗1∗1∗(1/2)

=>(A−B)=√3

thanks!

We have, dW = F→.dx→

= Fdx cos θ

= Fdx cos 60˚

= 1/2Fdx

= 1/2Kx^2

Therefore, W = K/2x1∫x2x2dx

= K/2[x^3/3]x1x2

= K/6(x2^3– x1^3)

thanks but I don't understand

Pressure is a force which acts on particular area.It's unit is "Pascal" (pa).

Pressure is an expression of force exerted on a surface per unit area.

The standard unit of pressure is the pascal (Pa).

pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. and it's S. I unit is pascal (pa).

Oops that question was sent by mistake !

thanks

By using:g=GM/R²so g₁=GM₁/R₁(gravity of planet 1)g₂=GM₂/R₂(gravity of planet 2)also M₁/M₂=V₁d₁/v₂d₂AS v=4/3 π r³M₁/M₂=V₁d₁/v₂d₂= R₁³ d₁/R₂³d₂--------equ(1)Therefore,g₁/g₂=R₁d₁/R₂d₂=(4/1)x(1/2) =2:1∴The accelerations due to gravity on the planets are in the ratio of

The inner planets, or terrestrial planets, are the four planets closest to the Sun: Mercury, Venus, Earth, and Mars.

Friction is usually called necessary evil. It means it is essential in the life and we cannot do any work without it.

Advantage of friction:-

a. Keeps the object at position :-by friction, the object can be placed at position and shaped.

b. Helps to move:-Friction forces help to move the object Ex: running or walking. With friction of feet/ shoes on the surface, helps to speed.

c. Frictional force helpsto move the object in the speed. For Example :- Spikes are used by the athletes to run fast.

d. Hold or grip an object:-With the help of friction the ridges of skin of our fingers and palm enable us to grab hold objects. For example- In badminton the players use grip to hold it.

e. Produce heat:-The law of conservation of energy states that the amount of energy remain constant. Thus, the energy that is due to friction in trying to move the object is really convert into heat energy.

Disadvantages of friction:-

a. Wear and tear of object:-due to friction, there is wear and tear of object. Lubrication is used to allow the parts to move easier, moreover, prevents wear and tear.

b. Wastage of Energy:-Excess of friction means extra energy, thus energy is being wasted.

c. Slow down the speed:-In the roller sketting, Rolling shoes and smooth surface are used to minimize friction.

d. Makes movement difficult :-Friction can make the job more difficult when one has to move the other object. Excess friction can make it difficult to slide a box across the floor, walk through deep snow.

PE = 1/2 k x^2

= 1/2 k (F/k)^2

= 1/2 F^2 / k

Since F is same, k is in the denominator,ratio : 2 : 1

A major problem in sending space probes toJupiteris that the planet has no solid surface on which toland, as there is a smooth transition between the planet's atmosphere and its fluid interior. Any probes descending into the atmosphere are eventually crushed by the immense pressures withinJupiter.

thank you

(a)Siriusit is not a planet of sun because it is a star but it is brightness star

sirius is not a planet of the sun but its a star

U = sqrt(2gH)= sqrt(2 × 9.8 × 0.25)

v = sqrt(2gh)= sqrt(2 × 9.8 × 0.04)

e = v / u= [sqrt(2 × 9.8 × 0.04)] / [sqrt(2 × 9.8 × 0.25)]= .2/.5

Coefficient of restitution is 0.40

(C) is correct option

option d) 5√2 m/s

Stars do not really twinkle, they just appear to twinkle when seen from the surface of Earth. The stars twinkle in the night sky because of the effects of our atmosphere. When starlight enters our atmosphere it is affected by winds in the atmosphere and by areas with different temperatures and densities. This causes the light from the star to twinkle when seen from the ground.

Merits:1. Glass can be prepared into different shapes and sizes.2. Glass used in the elevated buildings can be colourless or may coloured.3. Glass does not rust in moist air.4. Glass does not let water to pass through it.

Demerits:1. Glass is a very expensive material and it is cost effective.2. Glass is brittle in nature and thus it breaks easily.3. Glass can melt under very high temperature.

Answer: A force is surely being applied by the engine.

On a rough horizontal road, there is friction and we need to overcome the frictional force

So a force is surely being applied by the engine.

Answer is : A force is surely being applied by the engine

Only kirchhoff, s laws

Kirchhoffs Voltage Law or KVL, states that “in any closed loop network, the total voltage around the loop is equal to the sum of all the voltage drops within the same loop” which is also equal to zero. This idea by Kirchhoff is known as the Conservation of Energy.

Good

Urea is NH2- CO -NH2 ......( M.M = 60 )

No. of moles = Mass / Molar mass ...

Moles = 5.6 / 60 = 0.093 ....

No. of H atoms = N × Moles × 4 .... ( N is the avogadro number ....) ..

No. of H atoms = 0.093 × 4 × 6 × 10^23 ..= 1.116 × 10^23

What are the benefits of living in a society ? How it helps us in different spheres of life?

impulse has the unit Nsand dimensions same as that of momentum that is MLT^-1

my dear friend the answer is 3/2

because specific gravity is mass in air/mass in medium

60/40=3/2

hope you satisfied
